I checked out you city and yes, there is indeed a large 6x5 empty spot where DT would fit. That's why I don't quite buy your story. There is a large 6x5 hole in your city where DT should be. Right next to your Arc, CdM, and Winter Spire which also need to be collected daily. You didn't notice for a whole week? It took someone asking about prints for you to notice it was 'suddenly' missing?
On the other hand, just for fun, let's compare
@Stephen Longshanks's abuse scenario
above to your city as it exists today.
As has been stated repeatedly by players, DT is most useful for lower age players looking to sell higher age goods, or acquire goods to build higher level GBs. Given the moderate level of your GBs, including your level 25 Arc, it's clear you don't sell goods. Now that you're in FE, having now built both TA and HC, there's no real need for higher aged goods anymore, ad with HC replacing the supplies DT had supplied, why keep it? Especially when ...
Given your clear focus on the A/D GBs, having built no other GBs above your age other than Kraken, AO clearly seems to be the next GB to build. Now that you've likely acquired the goods to now build AO, DT has run clearly run it's course. Freeing up that 6x5 space will also make it much easier to fit in that 7x7 AO, which given it's size, made sense to build last.
Ready to now build AO, the FPs that used to sit on DT would surely have been nice to start leveling AO, especially with it giving daily FPs in return. Even more so if you're plan, as the top member of your guild, is to stay in FE indefinitely and farm GvG for point to build your guild's rank.
So, given the two scenarios, which one appears to 'fit' your current situation best?
- There's a bug in the system that randomly targeted you and just happened to delete your least useful higher age GB, just at the point it's no longer that useful and somehow, it really did take you over a week to notice. You do intend to rebuild it, (which you have not BTW, despite having the goods and BPs to do so.) and given your clearly under powered, poorly designed, fairly low FP producing city really could have used those FPs to get DT back to where it was. OR
- You deleted DT now that it's no longer useful and came up with the 'brilliant' idea that if you gave Inno some cock and bull story about it 'suddenly' disappearing, yada, yada, didn't register, yada, yada, must be a bug, yada yada, you'd maybe get those FPs back to get a jump start leveling the much more useful AO.
I'm going with scenario 2 ... 'cause something doesn't quite pass the smell test. I grew up in the country. I know when a cow's been around and it's time to get the shovel and knee high rubber boots.
